1. This invention relates to a spool for wire stranding machines, and it aims to provide va means which will simplify and expedite the spooling of wire in such machines, and one which will 'speed up production in assembly.

A further object is to provide a novel construction wherein the spool is made in interlitting separable sections having adjustable means to position the spool of wire and which also functions to hold the sections together and against separation, and further to provide in connection with the spool, novel braking mechanism.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a View in side elevation showing my improved spool in place in the frame of a wire stranding machine;

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a vertical sectional view taken on the line 3 3 of Figure 2;

Figure 4 is a vertical sectional view taken on the line 4 4 of Figure 2, and

Figure 5 is a horizontal section taken on the line 5-5 of Figure 2.

Referring specifically to the drawings wherein like reference characters designate like or similar parts throughout the different views, the spool has two main sections I Il. Each section I 0 has a relatively large disc or ilange II provided with a hubat I2. Such hubs at the inner ends have pairs of projections I3 which are intertted with each other and the outer ends of the hubs I2 are formed as trunnions I3 which are journaled in side members I4 of the frame I5 of a wire spooling machine. y

A coil of strand wire (not shown) is located between the discs or flanges II and on bars I6 of any desired number which are adjustably ymounted to assume different positions radially according to the size of the coil to be supported.

4 Claims. (01.4242-118) Such discs II preferably have radial 'slots I'I Y therein and the bars I5 have screw threaded shanks or terminals I8 located inthe slots for adjustment. Nuts I9 are threaded on the shanks I8 outwardly of the discs. Y

'I'he spool is mounted in the side members I4, as will be realized, for rapid rotation during the stranding operation and suitable braking means may be provided onthe spool. To this end, a brake drum 20 is mounted on either corrugated seat 2| of the hubs I2 so as to be rigid on the spool and to rotate therewith.

An expansible and contractile brake band 22 surrounds the drum 20 preferably having an inner rib 23 located in a peripheral groove 24 of the drum. This band is fastened at 25 to the frame I5 at one terminal, while the other terminal is free. Anchored to a stud 26 in the xed terminal of the brake band is a contractile coil spring 21 carried by a screw member 28 passing through a bifurcation or slot 29 in the free terminal of the brake band and above which a nut 30 is screwed onto the bolt 28 for adjustment to vary the tension of the spring 21 and control Y the action of the brake band accordingly.

In using the invention, the workman or spoolr, with the sections Ill disengaged, sets the coil or bundle of wire on one of the sections about the bar I6 and then securesthe other section to the first section through proper adjustment and tightening of nuts I9, and then places the spool with the assembled coil or bundle of wire thereon in the frame I5.` The machine will accommodate both fine and heavy wires and the method of spooling is eicpeditious and will overcome the necessity of stranding machines having to wait hours as is necessary under present conditions, incidental to the mounting or assembly ofthe bundle or coil ontoa spool.

It will lbe noted ythat the sections have a bore 3l therethrough. This enables a bar or rod to be passed therethrough when desired, and especially in handling or supporting either of the sections when detached from the other.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

1. A structure of the class described compris? ing hubs, opposed projections on the hubs separably engaged with one another, said hubs having integral discs, bars securing the discs together, land means clamping the bars to each disc for adjustment radially with respect to the discs, said bars and clamping means dually functioning as a bundle support and for retaining the hubs in engagement.

2. A spool of the class described having parts provided with hubs, the inner opposed ends of said hubs having projections, said projections beingseparably interfltted, discs integral on said hubs provided with radial slots, bars spanning the discs, said bars having 'Shanks extending through the slots, and securing nuts on the shank-s to clamp them t0 the discs to Yform an adjustable bundle support and detachable fastening means for retaining the hubs in interfitted en-` gagement.V

3. A spool of the class described having parts provided with hubs, the inner opposed ends of said hubs having projections, saidY projections being separably intel-fitted,` discs integral on said hubs provided with radialysiots, barsspanning the discs, 4said bars having Shanks extending through the slots, securing nuts on the shanks to Clamp them to the discs, a framefaV brake drurny pair of parts, said partsr each including a hub having projections on its inner end, said projections being interttednfor keying the parts to one another, a disc integral with each hub and having a pluralityof radial slots, bars spanning the discs and slidably engaging the slots to form a bundle support, clamping means for adjustably clamping the bars to the discs for varying the siZ'e of the=-bund1e-support and` for-seeuring-sthev hubs in inteiftted engagement. one? of: said^f hbs having a toothed portionjadjacent its outer end, a brake `drum having a part in intertted engagement on one of the hubs, a brake shoe carried by said Y frame operatively associated With'saiddruin,--arid trunnions on said hubs to enable mountngain. a frame, said bars and nuts formingianadju'st-i' able bundle support and a detachablefcornation for the hubs.

4. A spool of the class described comprising"a vvith thetoothed portion, trunnions on the outer `/erniseef jthehubsarframe in Which the trunnionseare ournaled, and afbrake shoe yieldablyV Yand aijlstbly supported by the frame and en- .gaging'over-thbrake drum.
